This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
So please show the code you used to execute the query!

The error is clearly telling you that you have missed supplying the parameter @CountryName in your query.

Please provide that in code.
